1. With the new digital balanced bridge technology, the maximum test current is 650ma, and the current accuracy is better than 0.1mA;
2. It can be used for ASTM C1202 and NT Build492.

3. The curve of each channel is displayed in real time , the test is more intuitive, and the results are calculated automatically after the test;

4. The new patented clamp can be used to make square and round test pieces;

5. Equipped with short circuit protection device, short circuit reminder and self recovery function;

6. The sensor adopts DB9 interface to avoid poor contact and easy insertion and extraction;

7. The test process is fully automatic control, and the voltage and current are controlled independently. Each channel can be input any voltage (current). It is convenient to compare the results of scientific research test.
